New Studies: Beneficial Effects Of “18-Hour Intermittent Fasting” On Health And Aging (NEJM)

From a New England Journal of Medicine online release:

In humans, intermittent-fasting interventions ameliorate obesity, insulin resistance, dyslipidemia, hypertension, and inflammation. Intermittent fasting seems to confer health benefits to a greater extent than can be attributed just to a reduction in caloric intake.

Evidence is accumulating that eating in a 6-hour period and fasting for 18 hours can trigger a metabolic switch from glucose-based to ketone-based energy, with increased stress resistance, increased longevity, and a decreased incidence of diseases, including cancer and obesity.

Preclinical studies and clinical trials have shown that intermittent fasting has broad-spectrum benefits for many health conditions, such as obesity, diabetes mellitus, cardiovascular disease, cancers, and neurologic disorders. Animal models show that intermittent fasting improves health throughout the life span, whereas clinical studies have mainly involved relatively short-term interventions, over a period of months.

How much of the benefit of intermittent fasting is due to metabolic switching and how much is due to weight loss? Many studies have indicated that several of the benefits of intermittent fasting are dissociated from its effects on weight loss. These benefits include improvements in glucose regulation, blood pressure, and heart rate; the efficacy of endurance training; and abdominal fat loss.

Health Research: Type 2 Diabetes Caused By “Overflow Of Fat” From Liver To Pancreas

From a Newcastle University news release:

“When fat cannot be safely stored under the skin, it is then stored inside the liver, and over-spills to the rest of the body including the pancreas. This ‘clogs up’ the pancreas, switching off the genes which direct how insulin should effectively be produced, and this causes Type 2 diabetes.”

Newcastle Clinical ResearchThis latest paper builds on previous Newcastle studies supported by Diabetes UK showing exactly why Type 2 diabetes can be reversed back to normal glucose control. Those studies led to the large DiRECT trial which showed that Primary Care staff can achieve remission of Type 2 diabetes by using a low calorie diet with support to maintain the weight loss.

A quarter of participants achieved a staggering 15 kg or more weight loss, and of these, almost nine out of 10 people put their Type 2 diabetes into remission. After two years, more than one third of the group had been free of diabetes and off all diabetes medication for at least two years.

In 2020, this approach to management of short duration Type 2 diabetes is to be piloted in the NHS in up to 5,000 people across England, and a similar programme is being rolled out in Scotland.

Healthcare Interviews: Centers For Medicare And Medicaid Services Director Seema Verma

Seema Verma, administrator for the Centers for Medicare and Medicaid Services, sits down for a rare one-on-one interview with special correspondent Sarah Varney of Kaiser Health News. They discuss President Trump’s plan for sustaining public health insurance programs, how the administration would respond if Obamacare is struck down by the courts in the future, and the latest Medicare for all proposals.

New Brain Health Books: “Successful Aging” By Daniel J. Levitin (Jan 7, 2020)

Successful Aging Daniel J. Levitin A Neuroscientist Explores the Power and Potential of Our Lives January 2020 Cover‘Successful Aging’ uses research from developmental neuroscience and the psychology of individual differences to show that sixty-plus years is a unique developmental stage that, like infancy or adolescence, has its own demands and distinct advantages. Levitin looks at the science behind what we all can learn from those who age joyously, as well as how to adapt our culture to take full advantage of older people’s wisdom and experience. Throughout his exploration of what aging really means, Levitin reveals resilience strategies and practical, cognitive enhancing tricks everyone should do as they age.

Author of the iconic bestsellers This Is Your Brain on Music and The Organized Mind, Daniel Levitin turns his keen insights to what happens in our brains as we age, why we should think about health span, not life span, and, based on a rigorous analysis of neuroscientific evidence, what you can do to make the most of your seventies, eighties, and nineties today no matter how old you are now.

Healthiest Adults: Early Risers With 7-8 Hours Of Sleep, No Insomnia Or Daytime Drowsiness

From a European Heart Journal study:

European Society of Cardiology logoWhen the five sleep factors were collapsed into binary categories of low risk vs. high risk (reference group), early chronotype, adequate sleep duration, free of insomnia, and no frequent daytime sleepiness were each independently associated with incident CVD, with a 7%, 12%, 8%, and 15% lower risk, respectively (Table 3). Early chronotype, adequate sleep duration, and free of insomnia were independently associated with a significantly reduced risk of CHD; while only adequate sleep duration was associated with stroke.European Society of Cardiology Sleep patterns, genetic susceptibity and incident cardiovascular disease a prospective study of 385,292 participants lowest risk factorsCardiovascular disease (CVD), including coronary heart disease (CHD) and stroke, is among the leading causes of mortality globally.1 In addition to traditional lifestyle behaviours, emerging evidence has implicated several unhealthy sleep behaviours were important risk factors for CVD.2,3 For example, short or long sleep duration,4–9 late chronotype,10,11 insomnia,12–17 snoring,18,19 and excessive daytime sleepiness20,21 were associated with a 10–40% increased CVD risk. European Society of Cardiology Sleep patterns, genetic susceptibity and incident cardiovascular disease a prospective study of 385,292 participants

New Study: Nearly 50% Of Americans Will Have Obesity By 2030, 25% Severely Obese (NEJM)

From a New England Journal of Medicine online study release:

The findings from our approach suggest with high predictive accuracy that by 2030 nearly 1 in 2 adults will have obesity (48.9%; 95% confidence interval [CI], 47.7 to 50.1), and the prevalence will be higher than 50% in 29 states and not below 35% in any state.

New England Journal of Medicine logo

Nearly 1 in 4 adults is projected to have severe obesity by 2030 (24.2%; 95% CI, 22.9 to 25.5), and the prevalence will be higher than 25% in 25 states. We predict that, nationally, severe obesity is likely to become the most common BMI category among women (27.6%; 95% CI, 26.1 to 29.2), non-Hispanic black adults (31.7%; 95% CI, 29.9 to 33.4), and low-income adults (31.7%; 95% CI, 30.2 to 33.2).

Projected National Prevalence of BMI Categories in 2030, According to Demographic Subgroup. New England Journal of Medicine December 2019

Although severe obesity was once a rare condition, our findings suggest that it will soon be the most common BMI category in the patient populations of many health care providers. Given that health professionals are often poorly prepared to treat obesity,27 this impending burden of severe obesity and associated medical complications has implications for medical practice and education.

In addition to the profound health effects, such as increased rates of chronic disease and negative consequences on life expectancy,25,28 the effect of weight stigma29 may have far-reaching implications for socioeconomic disparities as severe obesity becomes the most common BMI category among low-income adults in nearly every state.
